Abstract: In certain embodiments, a method includes receiving, at a payment server via an application executing on a device of a user, a request to create a payment proxy identifier. The method includes associating, in a data store maintained by the payment server, the payment proxy identifier to a financial account associated with the user. The method includes generating a personalized interactive element for initiating a transaction to the financial account of the user. The method includes receiving an indication of an intent to transfer a value from a sender to the user. The indication is produced via interaction of a device associated with the sender with the personalized interactive element. The method includes, responsive to receiving the indication, identifying a financial account of the sender and initiating a transfer of the value between the financial account of the user and the financial account of the sender.

Abstract: In some examples, a financial transaction is effectuated between first and second users of a payment service system. The payment service system receives, from the first user, a request for a first payment proxy identifier for the first user, and receives from the second user, a request for a second payment proxy identifier for the second user. The payment service system generates the payment proxy identifiers with a currency indicator prefixing one or more alphanumeric characters. The payment proxy identifiers enable the payment service system to identify the financial accounts of the respective users in lieu of payment card mechanisms. The payment service system receives a message from the second user indicating a money transfer request, initiates a transfer of funds from an account of the second user to an account of the first user, and sends an email message to the first user indicating the transfer of funds.

Abstract: In some examples, methods and systems may process one or more payment transactions between a merchant and a customer by establishing a short-range communication channel between a first computing device associated with a first user a second computing device associated with a second user. The method includes receiving, while the first computing device is offline with respect to a payment processing system, a fund transfer request from the second computing device, where the fund transfer request includes a payment proxy of the second user, the payment proxy having the syntax of a monetary currency indicator preceding an alphanumeric character. The method includes sending the fund transfer request from the first computing device to payment processing system after the first computing device establishes network connectivity with the payment processing system using a long range communication network protocol. The payment processing system processes the request unless the request has been previously authorized.

Abstract: This disclosure describes, in part, systems and techniques for providing digital receipts that may include itemized, interactive, and/or modifiable information about a transaction, such as a purchase transaction between a customer and a merchant. In various examples, a resource locator may be associated with transaction data and/or payment data. Furthermore, the resource locator may be associated with a storage location at which the transaction data and/or the payment data may be stored. In various implementations, the resource locator may enable access retrieval of data stored in the storage location to facilitate provision of an itemized digital receipt. Additionally, or alternatively, the resource locator may enable access retrieval of data stored in the storage location to facilitate provision of a response to an item-level information request.

Abstract: A fluid sample extraction device is disclosed comprising a housing defining an internal fluid passage having a distal open end and a proximal open end and a porous medium within the fluid passage, between the distal open end and proximal open end. The porous medium, which may be glass, is configured to allow fluid flow in the fluid passage to flow around the porous medium, toward the proximal open end of the housing, when fluid is drawn from the distal open end toward the proximal open end, and to allow fluid in the fluid passage to flow toward the distal open end of the housing, through the porous medium when the fluid is forced toward the distal open end. The porous medium is also configured to capture nucleic acids in the porous medium from the fluid when fluid is forced through the porous medium. Devices and kits are also disclosed.

Abstract: In some examples, a system generates an identifier for association with a user financial account. The identifier may have a syntax including a currency indicator and a string including one or more characters concatenated together such that the currency indicator appears immediately before the string. The system generates a user-defined identifier and maps, in a database, the user-defined identifier to the user financial account. The system receives a message indicating an intent to transfer funds from a sending user to a receiving user. The message may include the user-defined identifier in lieu of account information of the user financial account, to identify the user as the receiving user. The system parses the message to identify the user-defined identifier and accesses the account information of the user financial account using the identifier. The system initiates a transfer of funds from the sending user account to the user financial account.

Abstract: In one embodiment, techniques include systems and methods for facilitating context-aware peer-to-peer transfers of items utilizing at least one of short-range wireless technologies embodied by user devices or device-accessible contact lists. After receiving a request to transfer an item, a server can cause a device of a first peer user to detect devices of second peer users in the proximity of the device of the first peer user using short-range wireless technology. Based at least in part on the detected nearby devices or a contact list of the first peer user stored by the device of the first peer user, a second peer user to receive the item is determined. Upon receiving confirmation of authorization to transfer the item, requested and provided via an electronic message between the respective devices and the server, the item is disassociated from the first peer user and associated with the second peer user.
